Strong passwords are worthwhile measures to support confidentiality, integrity, and availability. Passwords should never relate to the user, for example, license plate, birthday, child or pet names, and should never be dictionary words. Passwords should combine upper and lower case letters, numbers, and special characters. Using the first letters of a meaningful phrase can make the password easier to remember. Your security policy will specify password length and aging. Aging defines how often you should change your password.
